The Parliamentary Under-Secretary of State for Environment, Food and Rural Affairs (Dr Thérèse Coffey)
Thank you, Mr Davies; it is a pleasure to serve under your chairmanship. I congratulate the hon. Member for Leeds North West (Alex Sobel) on having secured this debate, in which we have heard a number of interventions from other hon. Members. One might muse that time is running out for insects, but I assure Members that the Government understand that insects are crucial to our prosperity and wellbeing. The Royal Entomological Society estimates that there are over 24,000 species of insect—classified as six-legged animals with segmented bodies—in Britain. We know that they are vital to the food chain; they support many of our mammals and birds; and they play a fundamental role in much pollination, nutrient cycling, pest control and decomposition. The value of insect pollination to UK agriculture is estimated at more than £500 million a year.
As many hon. Members have observed, recent scientific papers and media reports have highlighted declines in insect populations and projected extinctions across the globe. We acknowledge that there have been long-term declines in the UK and globally, and there is no dispute about the seriousness of the issue, nor the need to take action. That is why, in the 25-year environment plan, we committed to improving the status of insects. I was also struck by Professor Sir Bob Watson’s comments in the media last week. He made it clear that we need concerted global action, but that extinction of insects within decades is probably unlikely, so we sometimes need to be mindful of the language we use to describe the evidence.
The Government report annually on how well different groups of insect species are doing, in partnership with academics and volunteer recording societies. That includes the UK-wide Pollinator Monitoring and Research Partnership, which is partly funded by the Department for Environment, Food and Rural Affairs. The Government’s indicators of the abundance of UK butterflies show long-term decline since 1976, but no significant change since 2012, and our indicator of pollinating insects in the UK tells a similar story. Overall distribution has declined since 1980, but has stabilised in recent years, although some individual species continue to decline. We are keeping those trends under review as encouraging, but not yet definitive, signs of progress.
Dr Coffey
I have so little time to respond to all the questions that I have already been asked, so I will do my best to answer the points that were made.
Our academic partnerships are helping us to deliver the most appropriate approaches to key factors affecting insect populations, such as habitat loss and fragmentation, invasive species, pests and disease, climate change and pesticide use; to understand the importance of other emerging potential threats, such as light or radiation; and to better define and predict the impact of climate change. I am conscious of hon. Members’ comments about how tackling climate change will also help biodiversity in insects.
We know that where we put habitat back, insects respond positively. For that reason, we are taking action to improve, extend and connect insect habitats. Over 1 million hectares of our best habitats for wildlife are protected as sites of special scientific interest, and we spend more than £50 million through agri-environment schemes to help bring more of those sites into favourable condition. Natural England reports that since 2011, over 130,000 hectares of land have been set aside to create new wildlife-rich habitats, largely through agri-environment schemes. In 2015, the Government introduced wildlife packages to those schemes, to make it easier for farmers to provide flowers to support pollinating insects and other insects on farms. There has been real progress for some species that landowners, NGOs and Government have collaborated to conserve, including supporting the re-introduction of lost species such as the short-haired bumblebee and chequered skipper butterfly. The environmental land management system that we are introducing, to which my hon. Friend the Member for Richmond Park (Zac Goldsmith) referred, will build on that by rewarding farmers and land managers for delivering environmental outcomes, such as protection of insect habitats.
In 2014, the Government published the national pollinator strategy, following a scientific review of the status of pollinating insects. That 10-year strategy sets out how Government, conservation groups, farmers, beekeepers and researchers can work together to improve the status of our pollinating insect species. Last week, we published an update to that review of the evidence base, which will inform our planned refresh of the pollinator strategy and, in turn, much of our action for other insect species.
In our 25-year environment plan, we committed to producing a new strategy for nature. That will take forward any new post-2020 global agreements on biodiversity, and bring together our biodiversity and pollinator strategies. I am conscious of the report to which the hon. Member for Brighton, Pavilion (Caroline Lucas) referred, but the Aichi 2020 targets are quite nebulous, and a lot comes down to judgment. I hope that when we come to the Conference of the Parties for the convention on biological diversity in Beijing next year, we will have more rigorous measures and indicators for targets for the global recovery of the environment, in particular biodiversity.
I know that there is concern about the impact of pesticides, including on insects. The Government carry out a thorough assessment of pesticide safety using the best scientific evidence before authorising their use, drawing advice from the Health and Safety Executive and the UK Expert Committee on Pesticides. Pesticides that carry unacceptable risks to pollinators are not authorised, as was the case with the science-led restrictions on neonicotinoids: outdoor use of three neonicotinoids was withdrawn from 19 December 2018.
We also need to take action against invasive species. Such action is largely focused on the Asian hornet: last year, the National Bee Unit located and destroyed four Asian hornet nests to tackle that threat to our native species, and surveillance continues. Our inspectors carry out about 6,000 apiary visits per year in England and Wales further to protect our honey bees. Advice and inspections help us to manage pests such as varroa, keep endemic diseases such as foulbrood at low levels, and keep other exotic pests such as the small hive beetle absent from the UK. The Bees’ Needs Week campaign, which happens every year in July, brings together expert partners to raise awareness of actions that all of us can take, whether we have gardens, window boxes, allotments or community gardens.
We have set out in the 25-year environment plan our step change in ambition for wildlife, in order to reverse declines. We have committed to improving protected sites and restoring new wildlife-rich habitats outside the protected site network. We are investing in peatland and woodland restoration as a contribution to climate change mitigation, which will also provide important habitats for insects and other wildlife; Members know about our investment in the northern forest. The nature recovery network will expand and connect our existing wildlife habitats by developing partnerships that can effect changes to land management at a catchment or landscape scale.
We are consulting on conservation covenants, which will be voluntary but legally binding agreements that would enable landowners to leave a permanent conservation legacy on their land. Such public commitments to taking positive actions to preserve and improve treasured features on their land, such as trees, woodland or flower-rich meadows, would be binding on future owners of that land and overseen by responsible bodies to ensure that land management obligations were delivered. I have already referred to the new environmental land management system, which will be the cornerstone of the country’s agricultural policy after we leave the EU. It is important that farmers are able to protect their crops, but also that people are protected from the risks that pesticides present, both to them and to the environment. It is therefore right to minimise the use of pesticides and to make the greatest possible use of other techniques, including non-chemical alternatives to protect crops.
I was surprised that the hon. Member for Leeds North West seemed to suggest that gene editing or GM could be used to modify crops. That is still a debate that matters, but it is important to highlight to hon. Members that we will continue to develop and refine our approach to pest control, with integrated pest management at its heart, minimising the need for pesticides. That approach combines different management strategies and practices to target and minimise the use of pesticides. The voluntary initiative scheme promotes and records IPM practices, and the uptake of that scheme is encouraging. It is important that we are able to protect crops, and such progress shows that the scheme works.
Regarding the introduction of a new environment Bill, I will give evidence to several hon. Members in about two hours’ time, so I am surprised that the hon. Member for Leeds North West has already declared what he thinks should happen with respect to scrutiny.
Dr Coffey
I am afraid I will not. The Government are open to this, and believe that what we have put forward is important. The policy paper that we published alongside the plan is an important indication of what else we want to achieve in that Bill.
Insect decline is a global problem that needs a global solution, which is why we will continue to play a leading role in the development of an ambitious strategy as we proceed. It is critical that we act now on the improving evidence base, internationally and at home, to ensure that we leave our environment in a better state for future generations.
